摘　　要：对北京地区东灵山、松山、雾灵山等13个保护区的植物物种的丰富度,植被类型多样性进行调查,其中松山保护区的物种数最多,有787种;喇叭沟门保护区群系类型最多,有26个。不同保护区之间的物种相似系数很高,大部分在0.6以上,群系类型的相似系数较低,大部分在0.5以下,说明不同保护区之间的群系类型存在一些差异,聚类分析结果基本与相似性系数分析的结果一致。根据相似性分析和聚类结果把北京地区划分为4个物种、植被类型相对较为一致的植物多样性保护区域。The survey on plant species abundance Donglingshan, Mt. Songshan and Mt. Wulingshan and vegetation types in 13 nature reserves including Mt. in Beijing area reveals that there are 787 species in Mt. Songshan reserve and 26 formations in Labagou reserve, which are the most in number. The species similarity index among different reserves shows high, most of which is above 0.6, but formation similarity index is low, most of which is below 0.5. These indicate differences exist in formation types among different reserves. The outcome of cluster analysis is basically identical with that of similarity index analysis. Beijing area is divided into 4 protected areas of plant diversity, in which there are relative identical species and vegetation types, according to the outcome of similarity analysis and cluster analysis.
